Description

Technical Field

[0001] The utility model relates to the technical field of tap water production and purification, in particular to flocculation purification equipment for tap water production. Background Art

[0002] Water purification refers to the purification process of removing pollutants from raw water. Its purpose is to filter impurities and microorganisms in the water body with specific process equipment. In order to ensure the water quality of the water body, the water plant usually performs a variety of filtration and purification on the transported water to remove impurities such as harmful substances in the water body. In the water purification process, the most common is filtration treatment. At present, in the water purification process of the water plant, sedimentation and filtration devices are usually used to complete the water purification work, such as sedimentation tanks. The sedimentation tank is a structure that uses sedimentation to remove suspended matter in the water. The equipment for purifying water quality uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter in the water. Sedimentation is a very important process in tap water production. Sedimentation is a process in which muddy water to be precipitated flows into a huge pool through one end, the muddy water flows slowly in the pool, and the clean water flows out of the clean water diversion channel at the other end.

[0003] However, when purifying water bodies, existing water plants have problems with incomplete purification and poor water quality. This is because in order to ensure the degree and efficiency of purification, sedimentation and filtration equipment usually pre-adds reagents to accelerate the coagulation of tiny suspended matter in the water body, thereby quickly producing flocculants and improving water quality through the sedimentation of flocculants. However, existing reagent addition usually pours the reagent directly into the water flow, which has poor mixing uniformity and weak reaction effectiveness, and cannot effectively flocculate and purify all water bodies. In addition, existing sedimentation tanks usually use self-sedimentation. When transferring the settled water body, it is very easy to generate a large disturbance force and pull some flocculants to rise and suspend and mix in the water body, causing the flocculants to transfer with the water body and affect the actual sedimentation effect.
